Every other sync

[galenwp]

It seems to me (and apparently others) that syncs only actually occur every other update. I don't think this happens immediately upon starting a pier, but after a few revs it's quite reliable. I can reproduce it with my node script that trivially pastes a file in to the pier repeatedly.

Basically, if you have a syntax error in your code it gets reported every other rev. The code for reproducing it with a script can be found in tlon/utils/copy. Common behavior is below.
